From Fox News:
The (15) members of Congress, led by Rep. Thomas Massie, R-Kent., signed onto an amicus brief in the Fifth Circuit Court of Appeals, where Texas inventor Cody Wilson is fighting a lower court ruling in favor of the government agency. The State Department in 2013, citing a law allowing it to regulate international arms trafficking, blocked Wilson and his nonprofit group Defense Distributed from posting technical data for 3-D printing of legal handguns.
Wilson has received more “friend of the court” backup from policy think tank Cato Institute and various free speech organizations.
